This study evaluated a scholarship support program, "Mathematics as a Common Language in Science," that was funded by the National Science Foundation (NSF). Running from 2015 to 2020, the scholarship support program assisted 31 students to major in chemistry, physics, or mathematics with the intent of supporting these students to enter…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

This study was guided by the question, how do we understand the multiplicative reasoning of upper high school students and use that to give insight to their performance on a standardized test? After administering a partial ACT assessment to a class of high school students, we identified students to make comparisons between low and high scoring…

This study proposes methods of reporting results of physics conceptual evaluations that more fully characterize the range of outcomes experienced by students with differing levels of prior preparation, allowing for more meaningful comparison of the outcomes of educational interventions within and across institutions. Factors leading to variation…

The roles of technology and education were at the forefront throughout the COVID-19 pandemic. This mixed-methods study examines the role of the three levels of the digital divide (i.e., access, capability, and outcomes) during the COVID-19 pandemic in Kentucky. We create and analyze a new multifaceted measure of district-level digital capacity to…

For this project, ACT developed math and science items that attempted to represent unique aspects of cultures, raise awareness of social justice issues, promote cultural learning, be authentic and relatable, be comprehensible, and represent people in positive, nonstereotypical ways. Creating culturally relevant items was a new challenge for ACT…

Beginning in September 2020, students will have the option to retake one or more sections of the ACT® test (referred to as section retesting, modular testing, or single-subject retesting), instead of needing to take the entire battery again. Section retests will only be available to students who have previously completed the full battery and only…

The goal of this study was to further evaluate the impact of IXL Math on math learning outcomes. Using a quasi-experimental design with matched treatment and control groups, this analysis utilized data from 312 public schools in Mississippi during the 2021-2022 school year. The middle school analysis included 272 schools (136 treatment, 136…

Problem Roulette (PR), an online study service at the University of Michigan, offers points-free formative practice to students preparing for examinations in introductory science, technology, engineering, and mathematics courses. Using four years of PR data involving millions of problem attempts by thousands of students, we quantify the benefits…

The goal of the paper is to understand to what degree the student success depends on teaching practices and materials, and to what degree it is due to differences in background, including prior knowledge, skills, preparation, abilities, etc. We analyzed the existing research on outcomes of the SAT and ACT in the United States and the Unified…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

American colleges are redesigning the ways in which they offer remedial courses, including mainstreaming students into college-level courses and making greater use of learning-technology to tailor the curriculum to students' specific academic needs. Exploiting a statewide cutoff on a remediation placement exam along with data on student outcomes…

The purpose of this study was to investigate the effects of completing career and technical education classes (CTE) during high school. In particular, the study sought to determine whether there were differences in academic scores of students who took CTE classes and those who took traditional high school classes. More specifically, the goals of…

The purpose of this study was to determine if the 1- and 2-term retention rates for students with the same ACT mathematics subsection scores were different between students who took a regular section of Probability and Statistics and students who took a learning support section of the same course. The subjects of this study were 2,714 students…

The study endeavored to determine if teaching test-taking strategies had an impact on the students' performance on the ACT science subsection exam. Students received test-taking strategies instruction for the ACT science subsection exam. Students were administered a pre-and post-test, confidence survey, and strategies ranking list. The study also…
